Description

    Technical field
  • The present invention relates to a base channel element and drainage assembly. More particularly, the present invention relates to a drainage assembly having adequate load bearing capacity and comprises of a plurality of base channel elements, drainage outlet fitting and end cap elements providing a water tight connection between adjacent elements. More particularly, it relates to the drainage channel assembly featuring a locking rib providing the flexibility of fixation and locking of the various frames and gratings/covers and a plurality of anchor bolts and a composite anchor plate for securing the drainage assembly into man-made surface areas while reducing the installation time of the drainage assembly.
  • Background art
  • Modular trench drainage assembly are well known in the prior art and typically consists of a plurality of base channels, open at the top and covered with grates, and recessed into a surface, such as a floor or the ground, commonly used to collect and direct rainwater to underground storm sewers to prevent flooding and to decrease runoff. Drainage assembly are available for various outdoor industrial and commercial sites with restricted depth such as indoor and outdoor multi-level parking lots, garages, podiums, balconies, terraces, etc.
  • The top opening of the drainage channel is usually covered with grating/cover and is flush with the surface to be drained. The channel segments are embedded in concrete within a trench prepared to receive the channel segments in proper order and with proper slope. The drainage assembly are usually installed on the surrounding surface. Thus, the choice of the channel element is an important factor in selecting the drain system for a particular application. The drain system is made up of variety of material for specific application to sustain for longer period without degradation. Various material that is utilized for manufacturing drain channels include galvanized steel, stainless steel, ductile iron, cast iron, pre-stressed concrete, composite resin, plastic, fiberglass, PVC, HDPE and, brass composite and similar kind. The channel material expands and contracts in accordance with the adjacent concrete ground. Therefore, the thickness and strength of the material depends on the application. The strength of the channel and grating/cover system is derived from its anchoring to the surrounding concrete. There is an increasing demand for modem drainage assembly with improved mechanical stability and ease of fixation.
  • A disadvantage of conventional trench drainage assembly is the potential safety hazard resulting from the lack of a connection, and removability between the grating/cover and the base channels. Because the grating/cover is unattached to the base frame member, unintentional, unauthorized or accidental removal of the top cover due to weight and force, such as a passing vehicle, is applied thereto, and thus, could result in injury to a pedestrian or damage to a vehicle or entry of undesirable debris into the drainage assembly.
  • Another disadvantage of the conventional trench drainage assembly is the distortion of the sidewalls of the base channels due to lack of mechanical stability, which adversely effects the connection between the adjacent channels and the grating/ cover leading to unwanted leakage of the water. In addition, the drainage assembly needs to be supported with fillers to provide mechanical stability and durability. Further, the channels should be light in weight and easy to carry and install with minimum people. However, there are many plastic drains and composite drains which are light but are very brittle and therefore break or cave in when the load is applied.
  • Thus, there is an increasing demand for the drainage assembly that are easy to manufacture and easy to install while ensuring improved mechanical stability and reliability of fixation. The present invention proposes a drainage assembly which would be versatile and meet all the needs mentioned above.
  • SUMMARY OF THE INVENTION

    DETAILED DESCRIPTION OF INVENTION
  • Various methods and apparatus embodiments of the invention are set forth below. While the invention is described with reference to specific preferred methods and apparatus including those illustrated in the drawings, it will be understood that the invention is not intended to be so limited. To the contrary, the invention includes numerous alternatives, modifications and equivalents as will become apparent from consideration of the present specification including the drawings, the foregoing discussion, and the following detailed description.
  • Fig. 1 of the accompanying drawings illustrates a schematic of the drainage assembly (100). It comprises of a plurality of longitudinally extending open-topped base channel elements (1) interconnected with the bottom connector (2) (as illustrated in Fig. 5(a) of the accompanying drawings). As illustrated in Fig. 6(a) the said bottom connector (2) connects at least two of the adjacent base channel elements (1) providing water tight connection between the adjacent channel elements (1). A sealant or adhesive may be used between the adequate surface of the said bottom connector (2) and the adequate surface of the said base channel elements (1) such that it provides large surface area for a water tight, permanent seal between successive base channels elements (1).
  • The construction of the said base channel elements (1) comprises of a bottom wall and a double layered side walls that extends upwards from the opposed edges of the bottom wall to form a trough for collecting and/or discharging water.
